BACKGROUNDS

In the field of smart home appliances such as smart televisions (TV), a near-field voice interactive mode is usually utilized as a way of interacting, for example, a Bluetooth voice interactor is utilized to interact with a smart TV. Although certain convenience is provided to a user in this way, it is still required to manually perform a Bluetooth connection, which means that user's hands cannot be truly liberated. Currently, an optimized interaction method is to control smart home appliances by using a far-field interactive mode, which is also suitable for smart TVs or far-field TV box devices.

However, in the current voice interaction technology, a user has to provide a wake-up prompt first, then speak out a search requirement. Especially when searching for video resources for playing, a user usually has to provide supplemental information multiple times to find out the content he wants to watch, and the user has to speak out wake-up words repeatedly every time he interacts, which is very inconvenient and leads to low search efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereafter, only certain exemplary embodiments are briefly described. As can be appreciated by those skilled in the art, the described embodiments may be modified in different ways, without departing from the spirit or scope of the present application. Accordingly, the drawings and the description should be considered as illustrative in nature instead of being restrictive.

Embodiment I

As shown in FIG. 1, in an implementation, a voice interaction method may include receiving a wake-up prompt at S10, activating an interactive mode according to the wake-up prompt at S20, displaying a dialog prompt identification in the interactive mode at S30, obtaining a vocal request, wherein the vocal request is input in response to the dialog prompt identification at S40, and displaying a requested content according to the vocal request at S50.

This embodiment is applicable to smart home appliances, such as smart TVs and smart air conditioners, and the like. Taking a smart TV as an example for illustration, firstly, a wake-up prompt, for example, “Xiaodu, Xiaodu, turn on the TV” is received. Then, the content of the wake-up prompt may be parsed. If the parsing results are messy codes, which means no clear content of a wake-up prompt is obtained, the interactive mode cannot be activated. Then, a user is prompted to speak out again a wake-up word for waking up the smart home appliance. The way of prompting to re-obtain a wake-up prompt can also be adaptively designed according to hardware of a smart home appliance. Taking a smart TV as an example again, if an indicator light turns blue and flickers, with its brightness being gradually weakened to none, it is a prompt that a wake-up prompt should be re-obtained so that the smart TV may be waken up.

When it is determined that the parsing result of a wake-up prompt includes clear wake-up words, the interactive mode may be activated, and an interface of entering the interactive mode may be displayed on the TV screen. This interface can be adaptively designed as needed. A dialog prompt identification is displayed then in the interactive mode, and its function is to remind a user to notice dialogue timer, to provide a requested content, to provide a search start prompt word and the like. The dialog prompt identification can be implemented in various manners and can be adaptively designed according to requirements. Furthermore, the designed position of the dialog prompt identification can also be adaptively adjusted, all of which fall into the protection scope of the present implementation. For example, the dialog prompt identification is designed as a dynamic circle displayed in the interface, which represents dialogue timer for a user. The dialog prompt identification may also be an animation designed as two cartoon figures interacting with a TV, which indicates that a user is prompted to provide a requested content. The dialog prompt identification may further be designed as a trumpet-shaped logo with keywords such as “Xiaodu”, which reminds a user to speak out the key words before starting a search.

After seeing the dialog prompt identification, a user can interact with a smart home appliance by providing vocal requests. For example, a vocal request provided by a user is “Xiaodu, Xiaodu, I want to watch a movie”. After receiving the vocal request, a voice recognition is performed, and the keyword “movie” may be obtained. In this case, the smart TV can perform a search by using the keyword “movie” or keywords which are related to “movie”, such as “hot movie”. After the search is completed, the search results of searching for “hot movie” are displayed in the interface, and a dialog prompt identification may also be displayed at the same time. If a further search is not required, the interactive mode is directly exited. If a further search is required, another vocal request can be continuously provided, until the requested content is found out, and then the interactive mode can be exited automatically.

Certainly, the voice interaction method according to the embodiment includes, but is not limited to, a method for interacting with a smart TV, it can also be applied to other smart home appliances such as a smart air conditioner. The process of interacting therewith is similar to the method mentioned above. Thus, no further details are provided herein again, all of which fall into the protection scope of this implementation.

In an implementation, after displaying the requested content, the method may further include displaying the dialog prompt identification again in the interactive mode, obtaining an updated vocal request, and displaying an updated requested content according to the updated vocal request.

In an example, after the requested content with regard to the keyword “movie” is displayed, a user can provide a further vocal request after seeing a dialog prompt identification. For example, the vocal request provided by a user can be “Hong Kong movie”. After receiving the vocal request of “Hong Kong movie”, a voice recognition is performed, and the keyword “Hong Kong” may be obtained. In this case, the smart TV can perform a search by using the keyword “Hong Kong” or keywords which are related to “Hong Kong”. After the search is completed, the search results of searching for “Hong Kong, hot movie” are then displayed in the interface of the smart TV, and a dialog prompt identification is displayed again.

For example, a vocal request of “gangster movie” is further provided by the user. After receiving the vocal request, a voice recognition is performed, and the keyword “gangster” may be obtained. In this case, the smart TV can perform a search by using the keyword “gangster” or keywords which are related to “gangster”, such as “police”, “gang” or “bandit”. After the search is completed, the searching results of searching for “Hong Kong, hot, gangster movie” are then displayed in the interface of the smart TV, a dialog prompt identification is displayed again.

Continuously, for example, a vocal request of “performed by Liu XX” is further provided by the user. After receiving the vocal request, a voice recognition is performed, and the keyword “Liu XX” may be obtained. In this case, the smart TV can perform a search by using the keyword “Liu XX”. After the search is completed, the searching results of searching for “Hong Kong, hot, gangster movie, Liu XX” are then displayed in the interface of the smart TV, a dialog prompt identification is displayed again.

Continuously, for another example, a vocal request of “next page” is provided by the user. After receiving the vocal request, a voice recognition is performed. In this case, according to the recognition results, the next page of the searching results is then displayed in the interface of the smart TV, and a dialog prompt identification is displayed at the same time again. After a further vocal request of “play the first one” is provided by the user, the corresponding program is played, and the interactive mode is exited automatically.

In an implementation, the dialog prompt identification may include a search prompt indicator, and the search prompt indicator may include a general search start prompt word and a preset dialogue timer.

The general search start prompt word includes a search start prompt word, such as “Xiaodu, Xiaodu”. The search start prompt word can be displayed all the time during the entire searching process or can be displayed only at the beginning of the searching process. The search prompt indicator may also include a preset dialogue timer, such as a time progress bar. A vocal request should be provided by a user within the preset dialogue timer. If no vocal request is provided by a user within the preset dialogue timer, the interactive mode is exited. Alternatively, if the search prompt indicator disappears, the current interactive mode is exited automatically, thereby avoiding mis-operation. The duration of the dialogue timer may be set to 1 minute or several minutes in advance, for example. An adaptive adjustment of the duration of the preset dialogue timer may be made according to different product types, all of which fall into the protection scope of this implementation.

In an implementation, the dialog prompt identification may include a content guide, and the content guide is used to prompt a user to provide a requested content relevant with the content guide.

The content guide is used to prompt a user to provide a relevant requested content after obtaining a vocal request each time during an interaction process. Taking a smart TV as an example, when a number of movies regarding “Hong Kong, hot, gangster, Liu XX” are searched out and displayed in the interface of the smart TV, the top ranked hot movie “Infernal Affairs” may be displayed in the content guide, which is used to prompt the user to directly provide a vocal request of “Xiaodu, Xiaodu, I want to see Infernal Affairs.” Alternatively, the user may also provide a vocal request of “Xiaodu, Xiaodu, I want to watch the third film, Chill” according to the content displayed on the current page.

As shown in FIG. 2, in an implementation, prior to S20, the method may further include determining whether a content of the wake-up prompt is associated with a preset interaction scenario, and activating the interactive mode according to the wake-up prompt, in a case that the content of the wake-up prompt is associated with the preset interaction scenario.

The wake-up words for different kinds of smart home appliances need to be associated with preset interaction scenarios. For example, the wake-up word for a smart TV may be “turn on the TV”, and the wake-up word for a smart air conditioner may be “turn on the air conditioner”. For a smart TV, using the wake-up word “turn on the air conditioner” will fail to be associated with the preset interaction scenario of the smart TV. Therefore, to avoid startup errors, it is important and necessary to determine whether a content of the wake-up prompt is associated with a preset interaction scenario.

As shown in FIG. 2, in an implementation, after S40, the method may further include determining whether a content of the vocal request is associated with a search request in the preset interaction scenario, and exiting the interactive mode, in a case that the content of the vocal request is not associated with the search request in the preset interaction scenario.

In an example, in the interactive mode of various scenarios, relevant search requirements associated with preset interaction scenarios may be stored. For example, in a preset interaction scenario of a smart TV, the stored relevant search requirements may be “Xiaodu, Xiaodu, I want to watch a movie”, “Hong Kong movie”, “I want to watch news broadcast” and the like. In a preset interaction scenarios of a smart air conditioner, the stored relevant search requirements may be “Xiaodu, Xiaodu, hot air” and the like. If, in the interactive mode of a smart TV, a user says search requirements which are not associated with the search requests in the preset interaction scenario of the smart TV, such as “Please set the temperature to 10 degrees” or “Please turn to the intermediate wind”, the current interactive mode is exited automatically.
